The Westminster Widget Company has an old machine that can produce 24 widgets in three hours. Now they have purchased a new
machine that can produce 48 widgets in four hours. Working together, how long will it take the two machines to produce 120
widgets?

Answers

9514 1404 393

Answer:

6 hours

Step-by-step explanation:

The old machine produces widgets at the rate of ...

(24 widgets)/(3 h) = 8 widgets/h

The new machine produces widgets at the rate of ...

(48 widgets)/(4 h) = 12 widgets/h

The total rate of production of the two machines is ...

(8 +12) widgets/h = 20 widgets/h

Then the time required to produce 120 widgets is ...

(120 widgets)/(20 widgets/h) = 6 h

Working together, the two machines can produce 120 widgets in 6 hours.

The nth terms of sequence 1 ; 5 ; 11 ; 19 is n² + n + -1 and the nth terms of sequence -2;-3; -6;-11; is -n² + 2n -3 .

What is quadratic sequence?

The differences (referred to as first differences) between every two successive terms are the same, then it is called an arithmetic sequence (which is also known as a linear sequence). But if the first differences are NOT same, and instead, the second differences are the same, then the sequence is known as a quadratic sequence.

According to the question

The sequence 1 , 5 , 11 , 19

First difference : 4 6 8

Second difference: 2 2

1.1.1>

Now, expression for the nth term of the sequence.

Quadratic equation

ax² + bx + c

at n= 1

a + b + c = 1 -----------------(1)

At n = 2

4a + 2b + c = 5 ------------------(2)

At n = 3

9a + 3b + c = 11 -------------------(3)

solving equation

Subtracting equation (3) from (2)

9a + 3b + c = 11

-4a - 2b - c = -5

5a + b = 6 ----------------------(4)

Subtracting equation (2) from (1)

4a + 2b + c = 5

-a - b - c = -1

3a + b = 4 ---------------------------- (5)

Subtracting equation (5) from (4)

5a + b = 6

-3a - b = -4

2a = 2

a = 1

Putting value in equation (5)

3a + b = 4

3*1 + b = 4

b = 1

Substituting the value in equation (1)

a + b + c = 1

1 + 1 + c = 1

c = -1

Substituting the value in the quadratic equation

x² + x + -1

For nth term

n² + n + -1

1.1.2>

Term of the sequence is 2549

Now,

using the nth term

n² + n + -1 = 2549

n (n+1) = 2550

n (n+1) = 50 * 51

n = 50

1.2> sequence of numbers is given: -2 ,-3 ,-6 ,-11

First difference = -1 -3 -5

Second difference = -2 -2

1.2.1 >

Now , expression for the nth term of the sequence.

Quadratic equation

ax² + bx + c

at n= 1

a + b + c = -2 -----------------(1)

At n = 2

4a + 2b + c = -3 ------------------(2)

At n = 3

9a + 3b + c = -6 -------------------(3)

solving equations

Subtracting equation (3) and (2)

9a + 3b + c = -6

-4a - 2b - c = 3

5a +b = -3 ----------------(4)

Subtracting equation (2) and (1)

4a + 2b + c = -3

-a - b - c = 2

3a + b = -1 -------------------(5)

Now,

Subtracting equation (5) and (4)

5a +b = -3

-3a - b = 1

2a = -2

a = -1

Putting value of a in equation (5)

3*-1 + b = -1

b = 2

Substituting values in equation (1)

-1 + 2 + c = -2

c = -3

nth term

-n² + 2n -3

1.2.2>the sequence of numbers will never contain a positive term.

because its first term is -ve and difference between consecutive term is always -ve. or as per nth term n² is a -ve term .

Hence, the nth terms of sequence 1 ; 5 ; 11 ; 19 is n² + n + -1 and the nth terms of sequence -2;-3; -6;-11; is -n² + 2n -3 .

The area of a pasture is 4200 m and the perimeter is 260 m. What are the length and width of the pasture?

Answers

Answer:

70 m and 60 m

Step-by-step explanation:

The formula for the area of a rectangle is length ⋅ width.

The area of the pasture of 4200 meters.

70 ⋅ 60 = 4200.

The formula for the perimeter of a rectangle is side + side + side + side.

The perimeter of the rectangle is 260 meters.

70 + 60 + 70 + 60 = 260.

Therefore, the length and width of this pasture are 70 meters and 60 meters.

Answer:

Soooooo, for Part A I got answer choice D.

I didn't want to overthink it like I normally do with everything else in life so i was like, there are 3 boxes on the side and 4 boxes on the bottom, so 3 times 4= 12.

Now i know that the area of the neighborhood is 12 blocks and 20 blocks equals a mile. 12 is obviously not 20, twelve is actually a little bit over half of twenty or .50%, so the best answer would be D.60%.

Riley purchased a 30-day International cell phone plan for use during winter break. There is a one-time fee of $35 and it includes 150 MB of data usage. Each extra megabyte,
or part thereof, of data costs $0.28. Find the cost of the plan if he uses 388 MB of data during the trip.

Answers

Answer:

the cost of the plan in the case when 388MB is used is $101.64

Step-by-step explanation:

The computation of the cost of the plan in the case when 388MB is used

Given that

One time fee is $35

And, it involves 150 MB of data usage

Also for the extra megabyte it charges $0.28

So for 388MB, the cost of the plan is

= $35 + 0.28 × (388 MB - 150 MB)

= $35 + $66.64

= $101.64

Hence, the cost of the plan in the case when 388MB is used is $101.64
